Cellometer Vision CBA image cytometry reveals the utility of the immunocompetent mouse model “Glowing Head” in assessing preclinical anti-tumor therapies

Introduction Preclinical models to evaluate therapeutic efficacy in the area of oncology have proven to be a challenge. The standard of preclinical assessment as always been immunosuppressed mice, but that model has not reliably predicted clinical efficacy [1]. Immunocompetent genetically engineered mice with tumor allograft models seem more promising, and yet reporter tags such as GFP and luciferase are targeted by competent immune systems, which may interfere with tumor growth and the response to therapeutics. Here, a collaborative group of researchers has created a reporter-tolerized genetically engineered mouse model, dubbed “Glowing Head” (GH), by targeting a luciferase-GFP reporter into the [...]

Iron oxide-based nanoparticles conjugated NuBCP-9 increase MCF-7 apoptosis as assessed by Cellometer Vision CBA Image Cytometer

Introduction The B-cell lymphoma-2 (BCL-2) family of proteins includes many key regulators of cell survival, cell death, and apoptosis. The deregulation of certain BCL-2 proteins is one of the first steps towards tumorigenesis and subsequent therapeutic resistance [1-4]. Targeting these BCL-2 family members is therefore an important area of oncology research [2, 4, 5]. Here, a collaboration of researchers has explored the targeting of these BCL-2 proteins with a BCL-2 binding peptide known as NuBCP-9 (FSRSLHSLL), which induces a conformational change in BCL-2 that alters the protein’s function from cell protection to cell killing. Researchers paired NuBCP-9 with iron oxide-based [...]

Evaluation of Nanoparticle-Based Therapy for Triple-Negative Breast Cancer using Cellometer Vision CBA

Introduction to Nanoparticle-Based Therapy for Triple-Negative Breast Cancer Tia Harmon and Dr. Ruben Gonzalez-Perez from the Morehouse School of Medicine and Emory University utilized the imaging and analysis capabilities of the Cellometer Vision to investigate leptin peptide receptor antagonist-conjugated nanoparticles in order to inhibit leptin signaling, a key pathway that promotes growth and survival of triple-negative breast cancer (TNBC) cells. It was hypothesized that these nanoparticles would first stop the expression of leptin’s downstream target Notch, and would thereby increase the effectiveness of standard chemotherapeutic compounds in limiting tumor cell survival [1-4]. Materials and Methods A human ER+ cell line (MCF-7) [...]

Using Cellometer Vision and Cyto-ID Stain for Autophagy Detection in Living Cells

It's White Paper Wednesday! This month's featured white paper: Using Cellometer Vision and Cyto-ID Stain for Autophagy Detection in Living Cells Our understanding of autophagy has expanded tremendously in recent years, largely due to the identification of the many genes involved in the process, and the use of GFP-LC3 fusion proteins to visually monitor autophagosomes and autophagic activity both biochemically and microscopically [1, 2]. Recently, a novel fluorescent probe, Cyto-ID ® Green autophagy dye, has been developed to facilitate the investigation of the autophagic process [3-5]. In this study, a novel method was performed using the Cellometer image cytometry in combination with Cyto-ID Green autophagy dye for [...]

Fast, accurate analysis of yeast, platelets, algae and other small cells

Acquire Fast, Accurate and Consistent Cell Viability and Concentration Measurements of Small Cells (2 microns or greater)! Obtaining consistent viability and concentration measurements for small cells like yeast, platelets or algae can be challenging. The Cellometers X1 and X2 can both perform bright-field and fluorescent counting of cells 2 microns and greater. X1 and X2 Cellometers are equipped with a 10X magnification lens. Both are capable of providing consistent concentration and viability measurements for cell samples that are 2 microns in size and greater. Both instruments are routinely used in laboratories around the world interested in studying small cells. See [...]
